Hypotheses: The investigators anticipate that common excipients do not cause bioinequivalence. 1) Hence, the hypothesize of this study is commonly used excipients in oral medications (tablets, capsules) modulate the rate or extent of Class 3 drug absorption and result in bioinequivalence. 2) Alternative hypothesis is that commonly used excipients in oral medications (tablets, capsules) do not modulate the rate or extent of Class 3 drug absorption and do not result in bioinequivalence.
